validates_uniqueness_of elasticsearch持久性

如何validates_uniqueness_of用於elasticsearch持久性。我有一個模型包含語句validates_uniqueness_of elasticsearch持久性

include Elasticsearch::Persistence::Model

我想包括像 validates_uniqueness_of :username

唯一性驗證當我試着用new功能 NoMethodError: undefined method validates_uniqueness_of for class

跟蹤

初始化

class Profile 
    include Elasticsearch::Persistence::Model 

    attribute :user_id 
    attribute :username, String, mapping: { index: 'not_analyzed' } 
    attribute :image_url 

    validates_uniqueness_of :username 

end

您可以粘貼代碼的位置嗎？也請分享任何可能有用的堆棧跟蹤。 – Val

添加stacktrace和類validates_uniqueness_of –

不改變Elasticsearch::Persistence::Model我基本上創建自己的驗證，因爲我沒有看到比presence其他任何驗證來定義。總之，您必須製作一個must search以確保它不存在

profiles = Profile.search query:{bool:{must:[{match:{username: "xxxxx"}}]}}

validates_uniqueness_of是class method of ActiveRecord

你Profile類應該使用elasticsearch-model這樣反而

require 'elasticsearch/model' 

class Profile < ActiveRecord::Base 
    include Elasticsearch::Model 

    attribute :user_id 
    attribute :username, String, mapping: { index: 'not_analyzed' } 
    attribute :image_url 

    validates_uniqueness_of :username 
end

我沒有使用任何常規數據庫和使用elasticsearch作爲持久性。另外根據這裏的文檔https://github.com/elastic/elasticsearch-rails/tree/master/elasticsearch-persistence你可以使用驗證'validates：title，presence：true' –

我在這裏問的是其他驗證我可以在這裏使用，我似乎沒有找到其他的東西 –

validates_uniqueness_of elasticsearch持久性
